The Write to Printer Display command lets you write a message of up to 16 characters to the second line of the printer display. For example, to write THIS IS TEXT to the display, enter the sequence ESC DLE STX THIS IS TEXT ETX. The display then shows the message THIS IS TEXT on the second line. A message is terminated by either ETX or upon reaching the sixteenth character.

Paper-Handling Operations

Hexadecimal:	1B	10	70	n

The paper-handling commands enable you to clear the current paper path or select various paper-loading options, where n is a value ranging from 30 through 33 hex. The value of n selects the following paper-handling options:

0(30H) = Load from current paper path

1(31H) = Clear current paper path

2(32H) = Load from front friction-feed path

3(33H) = Load from tractor-feed path

4(34H) = Load from top friction-feed path
